ALONZO HEAPS, OF DARBY, PENNSYLVANIA, ASSIGNOR T0 HIMSELF AND ENOS VERLENDEN, OF SAME PLAGE.

IMPROVEMENT IN RUB-ROLLS FOR CONDENSER-CARDS Specification forming part of Letters Patent N0. 149,124, dated March 31, 1874; application filed September 27, 1873.

T0 all whom Et may concern:

Be it known that I, ALONZO HEAPS, of

Darby, in the eounty of Delaware and St-aoe feather or spline formed. 011 it, and. so coustructed that it fits on the spindle of the rubroller nicely, and is secured by a nut 0r other means, so that it can be readily taken oif and another put on, so that a new feather can be put on when the old. one is worn out without disturbing the spindle, which, as heretofore arranged, had to be taken ofl' fromthe IO1ll to be repaired.

Figure 1 is a side elevation of a rubroller and spindle arranged according to 111y invention. Fig. 2 is a eross-seotion of the spindle 011 the line a; x, and Fig. 3 is a orossseotion of the tube on the same line.

A is the rub-roll; B, the spindle; C, the taube; D, the feather and E, the nut, by which the feather is fastened. 011 the spindle. From a point a little distanee from the end of the rubber I make ehe spindle as muoh smaller than the other portion as is needful for fitting on the taube, which is the sa-1ne size as the unreduced portion of the spindle. Said tube has the feather D so formed in it that the latt-er may be removable when worn by simply taking ofl one tube a1'1d putting 011 another. The inner end of the tube has a notoh, F, and the spind1e has a stud, G, engaging said. notch so that the rubber and 1she tube will be turned together.

The tube is hold up to the stud and on the spindle by the nut, whioh 1nay also be pinned if needed.

Time and labor are, by my invention, saved, since, in some cases an present, the rubber must be haken to a shop, the spindle detaehed, the o1d feather removed, the latter renewed, and. the spindle returned to the rubber. other cases the entire journal of the roll must be removed and replaoed.

Having thus desoribed my invention, I claim as new and desire 130 seeure by Letters Patent The feather D, of the spindle of a rub-roll,

applied detaohably 150 said spindle by a tube,

O, substantially as described.

ALONZO HEAPS.
